### Abstract

For fixed integers p, q an edge coloring of a complete graph K is called a (p, q)-coloring if the edges of every K_{p} ⊆ K are colored with at least q distinct colors. Clearly, (p, 2)-colorings are the classical Ramsey colorings without monochromatic K_{p} subgraphs. Let f(n,p,q) be the minimum number of colors needed for a (p,q)-coloring of K_{n}. We use the Local Lemma to give a general upper bound for f. We determine for every p the smallest q for which f(n,p,q) is linear in n and the smallest q for which f(n,p,q) is quadratic in n. We show that certain special cases of the problem closely relate to Turán type hypergraph problems introduced by Brown, Erdos and T. Sós. Other cases lead to problems concerning proper edge colorings of complete graphs.
